Chemistry problem
The volume of an ideal gas contracts from 5.68 L to 2.35 L as the result of a constant applied pressure of 1.48 atm. The system releases 733 J of heat during this process. Calculate deltaU (internal energy) for this process. Express answer in Joules. Please help, thank you ver...

An amount of 414.27 g of zinc sulfide (ZnS, MM=97.44 g/mol) reacts with 99.58 g of oxygen gas (O2, MM=31.999 g/mol) at a constant temperature of 298.0 K and constant pressure of 1.00 atm. The reaction: 2 ZnS(s) + 3 O2(g) --> 2 ZnO(s) + 2 SO2(g) dH = -818.58 kJ a) How much h...
